Title:
qemu-system-arm segfaults emulating versatile machine after running
debootstrap --second-stage inside vm
Status in QEMU:
Fix Committed
Status in “qemu-linaro” package in Ubuntu:
Fix Released
Bug description:
Binary package hint: qemu-kvm
As I'm now implementing the support for creating a rootstock rootfs
without requiring root, I need to run the deboostrap' second stage
inside a VM, to correctly install the packages into the rootfs.
qemu-system-arm fails right after debootstrap finish the second stage,
giving a segmentation fault.
Command:
qemu-system-arm -M versatilepb -cpu cortex-a8 -kernel vmlinuz -no-reboot
-nographic -drive file=qemu-armel-201007122016.img,aio=native,cache=none -m 256
-append 'console=ttyAMA0,115200n8 root=/dev/sda rw mem=256M devtmpfs.mount=0
init=/bin/installer'
